A Tilted Roller System for Laminated Products

ABSTRACT

A tilted roller system for preparing laminated products having different figures, including three-dimensional rolled figures, wherein said roller system comprises a conveyor band, a start roller band, a roller band and an unloading band.

OBJECT OF THE INVENTION

Present invention refers to a roller system for laminated products which present different figures from at least one type of mass and a combination of them, with the end goal of obtaining different tridimensional rolled figures, for the at least one of their later baking and frying.

BACKGROUND OF THE INVENTION

The rolling methods which exist in the industry only allow for the rolling of the laminated figure, without being able to achieve an open rolling or to control the degree of rolling of the laminated figure, so that the latter is always maintained closed and different figures with the same feeding direction and laminated shapes are not generated. These types of methods are very limited in the laminated shapes that can be developed, given that the rolling carried out by means of band sections placed vertically, and which rest over a horizontal band which is the one which feeds the laminated figures into the oven.

In a similar manner, application MX/a/2014/016071 divulges a rolling system for laminated products which comprises a horizontal conveyor band and a band for the start of the rolling, wherein said start rolling band is found in a perpendicular manner to the horizontal conveyor band.

Notwithstanding the rollers which are already known in the state of the art, the need still exists for rolling systems which allow for the carrying out of laminated products in different directions, mainly which will allow the controlling of the opening or closing of the rolling of the laminated product to be fed, as well as freeing the rolling at the desired point to achieve different rolled figures from the same laminated figure.

The exit end (102) of the feeding band (100) is found overlapped with the entrance end (201) of a conveyor band (200); said conveyor band (200) presents a horizontal parabolic shape, preferably convex on the upper part of the main support structure (20), said conveyor band (200) presents an exit end (202) opposite to an entrance end (201), a plurality of tracking rolling pins, a tightening rolling pin and a driving rolling pin, the tightening rolling pin is angularly displaced to tighten the conveyor band and in this way ensure its correct functioning, said displacement is undertaken preferably, by means of a first servo motor.

The exit end (202) of the conveyor band (200) is found in communication with the work surface (303) of a start roller band (300) set on an inclined plane towards the conveyor band (200), in such a way that it presents an inclination from between approximately 95° to approximately 120°, said start roller band (300) comprises a driving roller pin (301) and at least two tracking pins (302); said start rolling band (300) has the capability of displacing itself to at least one of a speed and a direction different from those of the conveyor band (200), the above in order to be able to undertake different types of rolling for the laminated products (1), said start rolling band (300) is found mounted unto a second mobile support structure (330), said mobile support structure (330) is found supported on a longitudinal guiding rail set on the main support structure (20) to longitudinally move the start roller band (300) in regards to the conveyor band (200), in such a way that said start roller band approaches/moves away from the conveyor band (200), this adjustment allows obtaining the desired aperture on the rolled product (2), this adjustment is crucial for achieving the rolling of the product, and is undertaken, preferably by means of a second servo motor.

A roller band (400) set on a descending inclined plane which presents an entrance end (401) and an exit end (402), the roller band (400) comprising a plurality of tracking rolling pins, and a tightening-driving rolling pin; the entry end (401) is found at a point which is higher than the exit end (402), similarly, said entrance end (401) is found under the exit end (102) of the conveyor band (200) and nearby to the work surface (301) of the start roller band; said roller band (400) is found mounted unto a third mobile support structure which is found mounted unto a vertical guiding rail, said vertical guiding rail is found mounted unto the second mobile support structure (330), in such a way that said roller band (400) moves vertically in relation to the start rolling hand (300), this adjustment allows the roller band to approach or move way towards the return of the unloading band (500). This adjustment allows ensuring and maintaining the desired aperture in the rolled product (2), and is undertaken, preferably by means of a third servo motor.

Given that the second and third mobile support structures (330) are found connected, upon the start roller band (300) approaching/moving away from the conveyor band (200), consequently, the roller band (400) also is approaching/moving away from said conveyor band (200), so that said roller band (400) has two movements, one being a vertical movement and the other a longitudinal movement.

An unloading band (500) which receives the laminated product (1) once it is rolled from the roller band (400), in addition to feeding the rolled product (2) to the next step of the process, whether it is baking or frying. Said band comprises an entrance end (501) and an exit end (502), a plurality of tracking rolling pins and one tightening-driving rolling pin, said unloading band (500) is found mounted unto the main support structure (20).

Said unloading band (500) presents at least four sections with different inclinations, a first section (510) with a substantially horizontal inclination, a second section (520) with an ascending inclination, a third section (530) with a substantially horizontal inclination and a fourth section (540) with a descending inclination, set on the lower part of the main support structure, which unrolls the rolled products.

In an additional embodiment, the feeding band (100) presents a length and a capability of being able to pivot, which allows transferring the laminated material without rolling from a laminated system (30) to the next step of the process, in such a way that the laminated material is not rolled.

Said feeding hand (100), when found at its lowest point, allows that: the exit end (102) is found in contact with the entrance end of the unloading band (500), given the pivot (111) which is in close proximity to the entrance end (101) of the feeding band (100) which goes up and down to establish contact with the exit of the laminated system.
